I’d question that too, except in my opinion, weed doesn’t smell nearly as bad as cigarettes or cigars. I expect the the same kind of restrictions will apply. However, with vaporizers becoming more popular for both nicotine and THC delivery, it’s not like you have to smoke it to enjoy.
reminds me of the story Rush tells about his vaping near a lefty once. she complained even after learning it was only water vapor. I think it just bothers some that people are enjoying something they diapprove of.
